Finally figuered it out:


#define SDADC_CR2_JEXTSEL_M(n) ((n)<<8)
#define SDADC_CR2_JEXTEN_M(n) ((n)<<13)
static const ADCConversionGroup adcgrpcfg1 = {
TRUE, // circular
ADC_GRP1_NUM_CHANNELS, // num_channels
adccallback, // end_cb
adcerrorcallback, // error_cb
&#46;u&#46;sdadc = {
/* CR2 ...

but there is no routine for initializing a timer channel for output compare when using the timer as GPT, is there?

Hi all

The SDADC on the stm32f37x supports timer triggering, e.g. trigger SDADC3 from TIM12_CH2. There is no implementation in HAL 16 for enabling timer triggering, has someone done that before? The only option i see now would be to disable ADC HAL and do everything by hand...

Thanks for the reply ...

Hi all

I think that the macro ADC_CR2_EXTSEL_SRC defined in adc_lld.h for setting the external trigger is wrong. The EXTSEL bits [2:0] are located on [19:17] in ADC_CR2.

Line 38:
#define ADC_CR2_EXTSEL_SRC(n) ((n) << 24) /**< @brief Trigger source&#46; */
should be
#define ADC_CR2_EXTSEL_SRC(n ...

WOW thank you very much, that solved the problem. I used https://github.com/ChibiOS/ChibiOS/blob/5c953ae7a200b9a2cd7c13f9cecd4d5aa7098d5f/testhal/STM32/STM32F3xx/USB_CDC/usbcfg.c

Hello guys

I'm new to chibios/rt so bare with me please.

I want to implement the chibi shell over usb CDC. everything compiles and runs, for one exception: the controller doesnt send the data immediatly to the PC but waits until some kind of send buffer is full and then sends it all to the ...
